How to Make a Will in Indiana: Requirements, Witnesses, and Common Mistakes

Indiana doesn't require an attorney to draft your will. It requires exact compliance with IC § 29-1-5-3. Miss a single requirement — wrong number of witnesses, missing declaration, signatures out of order — and a probate court can invalidate the entire document.

Here's every requirement and the specific traps that catch DIY planners.

The Five Legal Requirements

Under IC § 29-1-5-3, a valid Indiana will must meet all five:

1. Age and capacity. You must be at least 18 years old (or an active member of the US armed forces or merchant marine) and of "sound mind" — meaning you understand what property you own, who your natural heirs are, and what the will does.

2. Written document. Indiana does not recognize oral wills. Your will must be in writing — typed or handwritten. (Indiana does not recognize holographic wills without witnesses, so even a handwritten will needs proper witnessing.)

3. Your signature. You must sign the will yourself, or direct another competent person to sign in your physical presence and at your express direction.

4. Two witnesses. You must sign or acknowledge your prior signature in the physical presence of at least two competent, disinterested adult witnesses. "Disinterested" means witnesses should not be beneficiaries under the will, though Indiana is more lenient than some states on this point.

5. The declaration. This is the step most DIY templates miss: you must verbally declare to your witnesses that the instrument is your last will and testament. The witnesses must then sign in your physical presence and in each other's presence.

All five elements. Same room. Same time. In that order.

The Self-Proving Affidavit (Skip the Witness Hunt Later)

Under IC § 29-1-5-3.1, you can attach a self-proving clause that eliminates the need to track down your witnesses after your death. Without it, the probate court may need to locate your witnesses and obtain their testimony to validate the will — which becomes impossible if they've moved, become incapacitated, or died.

The self-proving affidavit requires the testator and both witnesses to declare, under penalties of perjury, that:

• The testator executed the will voluntarily
• They were of sound mind and legal age
• The signing occurred in the presence of both witnesses

Indiana does not require notarization for the will or the self-proving affidavit — the perjury declarations are sufficient. This is unusual; many states require a notary for the self-proving clause.

The Counterpart Execution Trap

If you can't physically be in the same room as your witnesses — common for remote families — Indiana allows "counterpart wills" under IC § 29-1-5-3(c). You sign one copy; witnesses sign identical copies in different locations.

This sounds convenient. It's actually the riskiest way to execute a will in Indiana:

• An Indiana attorney or directed paralegal must supervise the entire process
• All separately signed counterparts must be physically assembled into one document within 5 days
• The supervising attorney must sign an Affidavit of Compliance under penalties of perjury

If you execute a counterpart will without attorney supervision, the probate court can void it. For DIY planners, gathering everyone in one room is far safer than attempting the counterpart process.

What Your Indiana Will Should Cover

Beyond the legal formalities, a well-drafted will addresses:

Asset distribution. Who gets what — specific bequests (the house to your daughter, the investment account to your son) and a residuary clause that catches everything else.

Guardian nominations. If you have minor children, your will is the legal tool to nominate who raises them. Without this, the probate court decides.

Personal representative. Name who administers your estate (and a backup). This person handles probate, pays debts, and distributes assets.

Digital assets. Under Indiana's RUFADAA (IC § 29-1-8-1), you can grant your executor authority to access, manage, or delete digital accounts — email, financial portals, social media. Without explicit authorization, platforms can deny access.

What a Will Can't Do

A will only controls assets in your probate estate — property held in your sole name without a beneficiary designation. It has no authority over:

• Joint accounts with right of survivorship
• TOD deeds and POD accounts
• Life insurance and retirement accounts with named beneficiaries
• Assets held in a trust

If you assume your will controls everything, you may accidentally disinherit someone. Your beneficiary designations on non-probate assets override your will every time.

When to Update Your Will

Indiana doesn't limit how often you can amend your will. Major life events that should trigger an update:

• Marriage, divorce, or remarriage
• Birth or adoption of a child
• Death of a named beneficiary or executor
• Significant asset acquisition (home purchase, inheritance, business)
• Moving to Indiana from another state (your old state's will may technically be valid, but Indiana-specific provisions won't be covered)

You can amend with a codicil (a formal amendment) or execute an entirely new will that revokes the prior one. For significant changes, a new will is cleaner.

The Indiana Basic Estate Planning Kit includes step-by-step will drafting instructions tailored to Indiana's execution requirements, including the self-proving affidavit format and a checklist to avoid the most common invalidation errors.
